Platelets of only 17×10^9/L means that serious bleeding may occur in the organism at any time, which is a more dangerous situation, and you need to go to the hospital in time to do the relevant examination and treatment. Reduced platelet count is common in patients with primary immune thrombocytopenia, aplastic anemia, acute leukemia, systemic lupus erythematosus, and severe liver disease. Platelets are the more important blood cells in human blood, and play a very important hemostatic function in pathology and physiology. Platelets 17 × 10^9/L is significantly lower than normal, the body’s hemostatic function is significantly reduced, prone to a variety of bleeding. For example, when bleeding occurs without trauma, patients show bleeding spots and petechiae on the skin and mucosa, and in severe cases, bleeding from the nose and gums. Even craniocerebral hemorrhage may occur, and patients will have headache, nausea, vomiting, etc., which is easy to endanger life. Therefore, patients need to consult a doctor in time to find out the cause of thrombocytopenia and receive corresponding treatment under the guidance of physicians.
